Application filed May 4,

Our invention relates to switches and switchboard panels and it relatesparticularly to switching devices for elatively high-voltage circuits.

The object of our invention is to provide a switching device, of theabove-designated character, which may be constructed 0t such standardparts as are employed in ordinary insulating and switchboardconstructions and in such manner as to provide a structure that may beadapted to a series of switches de signed for a large range of voltagevalues by merely changing certain minor portions of the apparatus.

A further object of our invention is to provide a switchboard panelwhich may be constructed of structural iron and the like and the designofwhich is readily adaptable to switches of various capacities and toswitches of diflerent voltages.

Heretofore, it has been customary, in the construction of panels of theabove-indicated character, to employ base members of insulating materialon which the various switching devices are mounted.

In accordance with our invention, we provide a panel constructed ofstructural iron on which the various switch members are mounted and fromwhich they are insulated by means of standard insulating structures ofthe kinds employed in various other forms of apparatus. Furthermore, ourstructure is of such flexible design that it may be arranged toaccommodate any one of a relatively large series of switch designshaving difl'erent numbers of contactors and arranged for wide ranges ofvoltage and current values.

Fig. 1 of the accompanying drawing is a front elevational view of aswitching device constructed in accordance with our invention; and Fig.2 is a side elevational view of the device shown in Fig. 1.

The drawings illustrate a panel 1, or frame, of structural iron on whicha pair of auxiliary panels 2 and 3 are mounted and insulated therefromby insulators 4 and 5. A stationary switch contact member 6 is mountedon each of the auxiliary panels 2 and 3, and a movable contact member 7is actuated into and out of engagement with each of the stationarycontact members 6 by means of an actuating device 8.

The structural framework 1 comprises a 1920. Serial No. 373,?92.

pair of upright channel members 9 and 10 that are mounted on a basemember 11 oi channel shape and are connected by a top angle iron 12 andby an intermediate plate 13.

The framework 1 should be of a construction that will permit ofco-ordination of aseries of like panel members in such manner as tocompose a complete switchboard.

Each of the auxiliary panels and 3 is of insulating material and thepanels are mounted on insulators i and 5 in order to eiiectivelyinsulate the electrical devices that are mounted on the auxiliary panelsfrom the structural framework and to dispose the panels in spacedrelation upon the framework 1.

An arc-blowout shield 14, which is mounted on each of the panels 2 and3, comprises a blowout coil 15 and magnetic side-plate members 16therefor. One terminal of each of the blowout coils 15 is connected to aterminal member 1? by means of a bolt 18 and a conductor 19. Theremaining terminal of each of the coils 15 is connected to thecorresponding stationary contact member Each of the stationary contactmembers 6 is secured in place by means of a series of bolts 20 thatserve, also, to secure the auxiliary panels 2 and 3 to the insulators 5.

The movable portion of each of the switch mechanisms embodies a contactmember 7 that is pivotally mounted on a bracket member 24 by means of apin 22 and is yieldingly held in position by a spring 23, in a familiarmanner. The contact member 7 is electrically connected to a terminalmember 25 through a bolt 26 and a flexible conductor 27. The severalbolts 26 extend through insulators 28 that are respectively mounted onthe channel members 9 and 10. The bracket members 24s are mounted onrods 29 of insulating material, such, for example,

as micarta rods, which are clamped to a,

transverse rod 30 by means of respective sets of clamping jaws 31.

The actuating mechanism 8 comprises a core member 32, two coils 33,which are mounted on the respective legs of the core member 32, and anarmature member 34. The armature member 3 1 is supported by an arm thatis clamped to the transverse rod 30. Bearing members 36 and 37, whichare mounted on a base member 38, constitute supports for the transverserod 30. lhe base member 38 supports the core mem ber 32 of theeleetroinagnet.

An additional panel 39, preferably of insulating material, is mounted onthe lugs l of the base member 38 and is secured to the frame 1 by means01" the bolts ll.

The panel 39 constitutes an insulating base on which any auxiliaryapparatus, such, tor instance, as relays, meters and the lilce, may bemounted in order to complete a control unit that embodies the relativelyhigh-voltage switching members.

The trame 1 may be maintained in an up right position by a depending leg42 that connected, at one end, to the cross menn ber l8 and, at otherend, to the floor.

The partici ar uti y of the switching device hereinbe'tore defnibed willbe appre ciated when it is pointed out that the insulating members l a lare of a type fie quently employed for odier purposes in electricalinstall-mini and which may be procured tor a relatively large series ofvoltage values, and that the voltage for which the switch is to he useddetermines the type of insulator support to be en'iployed.

It will be understood that, by a mere change of the insulating membersl, 5 and 2% and by the use of insulating rod of .-'ving le ths, aswitching device may be provided ror any desired voltage withoutcumloying other than a. standard series of panel nicn'ibers or framemembers. Another item of importance is the fact that the actuatingmechanism 8 is not insulated -irom the frame work anc, therefore, is notsubjected to relatively arge values of voltage, as is the case in suchstructures as have heretofore been provided.

The required change in the length oi? the insulating rods 29 may becompensated -for by moving the base member 38 upwa 'dly or downwardly inaccordance with the position necessary to provide accurate coactionbetween the movable contact members 7 and the stationary contact members6.
